毒液之力

有毒的刺

锋利的刺带着毒液。踩到或抓住它会很疼。

它的毒液会造成什么？

The spines on its fins produce venom. In a study of a related rabbitfish, the venom was found to be similar to stonefish venom.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

When eaten, it has been linked to cases of mild ciguatera-like poisoning. Ciguatera is a form of food poisoning caused by toxins in some reef fish.1

它害怕时会做什么？

When threatened, it stops suddenly and raises its dorsal, anal and pelvic fins, showing an array of venomous spines around its body.1

如果它的刺扎到你

把伤口泡在热水里，水温以不烫伤为限、尽量热（先用你自己的手试一试），泡 30 到 90 分钟。去看医生，尤其是被石头鱼和魟鱼伤到时。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果它的刺扎到你：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

Its spines are mainly a defence against predators. The highest predation pressure falls on its larvae and planktonic stages.1

It came to the Mediterranean through the Suez Canal. It was first recorded off Israel in 1955 and has since spread as far west as the French Mediterranean coast and the Adriatic Sea.1

It is a daytime feeder. At night it hides in cavities in the reef.1

It is an important fish for fisheries in the Mediterranean. In Kenya, it is caught mainly as bycatch.1
